Britain today said that Prime Minister David Cameron stands by his remarks asking Pakistan to stop exporting terror. An official spokeswoman on the eve of Pakistan President Asif Ali Zardari's official visit to the United Kingdom said that Cameron will not back away or apologise for his remarks. She said that the British Prime Minister was referring to elements within Pakistan supporting terrorism and not the Pakistan government. She was talking to media after the British High Commissioner in Islamabad Adam Thomson had been summoned by Pakistan Foreign Minister Shah Mehmood Qureshi.Earlier, media reports in London quoting Downing Street sources said that Cameron would not back away from his comments on Islamabad exporting terror as he meant it. Relations between London and Islamabad soured last week when Cameron while on an official visit to India said Pakistan could not be permitted to look both ways in promoting the export of terror, while publicly working for stability in the region.His strong comments came after a massive US intelligence leaks that alleged links between Pakistan's powerful ISI and Taliban terror group in Afghanistan.The stand-off between the two countries came as Zardari arrived in Paris for a five-day difficult trip to Paris and London.
